Housing molded product made of fiber-reinforced thermosetting resin and its manufacturing method

繊維強化熱硬化樹脂製筐体成形品およびその製造方法

Abstract

【課題】飛躍的に力学特性、剛性、成形性、軽量性に優れるとともに、天面部分以外の複雑な形状を有する側面部分をも含めた全体が一体で成形され、更にボスリブ等の接続部分の問題も解決した繊維強化熱硬化樹脂製の筐体成形品およびその製造方法を提供する。 【解決手段】本発明の繊維強化熱硬化樹脂製筐体成形品4は、強化繊維にマトリックス樹脂として熱硬化性樹脂が含浸された繊維強化熱硬化樹脂製組成物を部品として含む筐体成形品であって、前記部品は、少なくとも平面部分1と、この平面部分に連なる立壁部分2A〜2Cとボスリブ3部分とを有すると共にこれら両部分2A〜2C、3が前記平面部分1と一体成形され、かつ、前記平面部分1と立ち壁部分2A〜2Cとはいずれも前記繊維強化熱硬化樹脂製組成物で構成されており、前記平面部分1のJIS K7074(1988)で規定する曲げ剛性強さが40GPa以上である。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a housing molded product made of a fiber-reinforced thermosetting resin made drastically excellent in dynamic characteristics, rigidity, moldability and lightweight properties, integrally molded as a whole inclusive of a side part having a complicated shape other than a top panel part and solving the problem of a connection part such as a boss-rib or the like, and its manufacturing method. SOLUTION: This housing molded product 4 made of the fiber-reinforced thermosetting resin includes a composition made of the fiber-reinforced thermosetting resin, wherein reinforcing fibers are impregnated with a thermosetting resin being a matrix resin, as a component. This component has at least a plane part 1, the erected wall parts 2A-2C continued to the plane part and boss-rib parts 3, and both parts 2A-2C and 3 are integrally molded along with the plane part 1 and both of the plane part 1 and the erected wall parts 2A-2C are constituted of the composition made of the fiber-reinforced thermosetting resin. The bending rigidity strength prescribed in JIS K7074(1988) of the plane part 1 is 40 GPa or above. COPYRIGHT: (C)2005,JPO&NCIPI
